WebTo calculate the pounds of Biochemical Oxygen Demand (BOD) or suspended solids (SS) removed each day, we need to know the mg/L BOD or suspended solids removed and the plant flow, then we can use the mg/L to lb/day formula: BOD removed, lb/day = BOD, mg/L x Flow, MGD x 8.34 lb/gal Example: WebSeed Factor (mg/l) Used to correct the BOD test for oxygen depletion resulting from the presence of seed. Seed correction per ml is derived from seed control tests, then multiplied by the amount of seed used in the test, as in Equation 6. If there is no seed used in the test the seed factor is zero. costume bowlingWeb• Select a Seed Source • Determine if you will be seeding a BOD or CBOD • Set Sample up as you would a normal BOD/CBOD • Incubate for 5 days • Calculate the mg/L of … costume bowler hat
